Dracaena plant named ‘LIMÓN’

ABSTRACT

The variety ‘LIMÓN’ is a new and distinct cultivar of  Dracaena deremensis  plant. It can reach 75 cm height in a 21 cm diameter pot, with an average of approximately 34-40 leaves per plant. The arrangement of the leaves is base wrapped around the stem. Shows a dark green colored foliage, with marginal light green stripes.

Latin name of the genus and species of the claimed plant: Dracaenaderemensis.

Variety denomination: ‘LIMÓN’.

BACKGROUND

The present invention relates to a new and distinct cultivar of Dracaenaplant, botanically known as Dracaena deremensis of the family ofAsparagaceae, hereinafter referred to by the cultivar name ‘LIMÓN’.

Dracaena is a monocotyledonous and tropical foliage plant which can beproduced as a single or multi-stemmed plant, used mainly as a houseplant for interior use or outdoors in shades in zones 9 or 10 only.

The new Dracaena ‘LIMÓN’ originated as a naturally occurring whole plantmutation of Dracaena deremensis variety ‘LEMON LIME’ (unpatented). Thenew Dracaena ‘LIMÓN’ was discovered and selected by the inventor,William Vásquez Ulate, in 2020, as a single sprouting plant within acontrolled environment, in Candelaria, Palmares, Alajuela province,Costa Rica.

‘LIMÓN’ was grown in tropical lowlands in Costa Rica with day lengths of12 to 13 hours and ambient temperatures of 65 to 85 degrees Fahrenheit.The light levels in lux were 30 K and the level of relative humidity was80%.

Asexual reproduction of the new Dracaena ‘LIMÓN’ by vegetative cuttingswas first performed in 2020 in Candelaria, Palmares, Alajuela province,Costa Rica, and demonstrated that the combination of characteristics asherein disclosed for the new cultivar are firmly fixed and retainedthrough successive generations of asexual reproduction.

SUMMARY

The following traits have been repeatedly observed and are determined tobe unique characteristics of ‘LIMÓN’, which in combination distinguishthis Dracaena as a new and distinct cultivar:

-   -   1. Dark green colored foliage, and light green color stripes in        the margins of the leaf    -   2. Wide and lanceolate leaves, 40-45 cm long and supported in a        rosette.    -   3. 0.5 m-0.75 m plant height in a 21 cm diameter pot.    -   4. Erect Plant habit.

Plants of the new Dracaena ‘LIMÓN’ differ from plants of the parentalcultivar, Dracaena deremensis ‘LEMON LIME’ (unpatented) in thecharacteristics described in Table 1.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying photographs illustrate the overall appearance of thenew Dracaena deremensis cultivar ‘LIMÓN’ showing the colors as true asis reasonably possible with colored reproductions of this type. Colorsin the photographs may differ slightly from the color value cited in thedetailed botanical descriptions which accurately describe the color of‘LIMÓN’.

DETAILED BOTANICAL DESCRIPTION

The new Dracaena ‘LIMÓN’ has not been observed under all possibleenvironmental conditions. The phenotype of the new cultivar may showphenotypical changes with variations in environment such as temperature,light intensity, and day length without any change in the genotype ofthe plant.

The aforementioned photographs, together with the followingobservations, measurements and values describe the new Dracaena cultivar‘LIMÓN’ as grown in open-field conditions at Baltimore, Matina, Limónprovince, Costa Rica, which closely approximate those generally used incommercial practice. Average temperature in Baltimore is 31° C. duringthe day and 24° C. at night. Plants grow under natural light conditions.

Plants of the new Dracaena cultivar ‘LIMÓN’ are grown under lightconditions of about 80% shade from natural sunlight and about 80%relative humidity. No supplementary artificial light is necessary.Plants of the new Dracaena ‘LIMÓN’ are given 1) a liquid 24-8-16fertilizer every 15 days, and 2) a granular Nutricote 18-6-12 fertilizerevery 6 weeks in raining season. No growth retardants are used whengrowing plants of the new Dracaena ‘LIMÓN’.

Color references were made according to The Royal Horticultural SocietyColour Chart (RHS) online (rhscf.orgfree.com). The photographs anddescriptions were made during the dry season in Candelaria, Palmares,Alajuela province, Costa Rica when outdoor day average temperature was31° C. The age of the plants described is 8 months old.
